Lightweight and intuitive javascript library

// [INTERNAL USE ONLY]

// Handle attributes for the matched elements
u.prototype.attr = function (name, value, data) {
  data = data ? 'data-' : '';

  // This will handle those elements that can accept a pair with these footprints:
  // .attr('a'), .attr('a', 'b'), .attr({ a: 'b' })
  return this.pairs(name, value, function (node, name) {
    return node.getAttribute(data + name);
  }, function (node, name, value) {
    node.setAttribute(data + name, value);
  });
};
